Title: Adjusting mechanism of distribution of water flow rate in laminar flow nozzle
Inventor: EBATA SADAO
IPC: C21D1/667
Filed: 1982-03-16
Abstract: PURPOSE:To change the ratios in the flow rates of releasing water in the central part and both right and left end parts at any time by holding headers juxtaposed with plural laminar flow nozzles freely movably upward or downward by means of actuators, and tilting the headers to an optional angle. CONSTITUTION:Headers juxtaposed with plural laminar flow nozzles 5 in a longitudinal direction are held freely movably upward or downward by means of actuators 6. The headers 4 are tilted around the pins of pivotal supporting brackets 8 by the operation of the actuators 6, whereby the ratios in the distributions of the flow rates of the water released from the respective nozzles 5 are changed as desired. Thus, even if there are gradients in the initial temp. in the transverse direction of the plates 3, the end temp. of cooling is made uniform simultaneously; therefore, the cooled steel plate 3 having uniform texture is obtained.

Title: Demodulating circuit of address signal
Inventor: MIURA YOSHIO
IPC: G11B7/005
Filed: 1984-03-05
Abstract: PURPOSE:To detect precisely only address data by presetting positions on which start and end patterns are to be detected to respective counters, and using a signals detected at the preset positions or their substitutive signals. CONSTITUTION:A preamble B, address mark D and a post data G of a reproduced address signal obtained from an optical disc are supplied to an FF circuit 27'. Positions where the mark D and the data G are to be detected by FFs 34, 35 respectively are preset in counters 30, 36 respectively. An AND circuit 32 detects the mark D arriving at the position within the output period of a window signal E and an AND circuit 33 outputs a carry of the counter 30 as the mark D or its substitute. Similarly, an AND circuit 39 outputs the data G or its substitute. Therefore, the address data can be detected by using the output of an FF40 only within the period from the detection of the mark D to the detection of the data G. Thus, a precise address signal can be demodulated.

Title: Receiving circuit for amplitude-modulated wave
Inventor: HIRASHITA TAKEMASA
IPC: H03G3/30
Filed: 1980-03-29
Abstract: PURPOSE:To reduce automatically the low-frequency output of a disturbing wave component, by decreasing the output level of a low-frequency amplifier on detecting an AGC voltage exceeding the level at which normal automatic gain control is exercised. CONSTITUTION:When a desired wave is received, AGC is exercised, so that AGC voltage V will never reach level L. When a disturbing wave is inputted, on the other hand, AGC is not exercised and if it exceeds input level D', output IO of intermediate frequency amplifier 6 exceeds level C'. If the input level exceeds M, however, AGC voltage exceeds detection level L, so that detecting circuit 13 outputs a signal on detecting that. The detection signal is inputted to low-frequency amplifier 8 via control circuit 15. The output of amplifier 8 is therefore reduced automatically and the output of an unnecessary disturbing wave component is reduced.

Filed: 1985-03-04
Abstract: PURPOSE:To find the three-dimensional shape of an object body with precision by calculating a body presence area while considering that an input image from an image pickup device is a perspective projection. CONSTITUTION:An area in a conic shape which has a vertex at an observing point 2a and an image 3a as its bottom surface is regarded as the object presence area 4a in the direction of a line of sight, the image 3a is enlarged or reduced by normal three-fin conversion in a plane parallel to a yz plane, and this is repeated in the (x) direction by I times while the magnification is varied. For example, an image 5d projected on the yz plane 5b is obtained by reducing the picked-up image 3a and an image 5c is obtained at the position of the yz plane 5a similarly. When the object presence area is found in the one direction of the line of sight, an area common to an object presence area 4b in the direction of another line of sight is found. This operation is repeated by (n) times and object presence areas of direction of all lines of sight are ANDed to obtain the three-dimensional shape of the body.
